The technology to economically harvest lower wind speed regions is already coming online. This means there remains huge untapped potential throughout the EU, and the turbines designed for just that are already being installed for the past few years.

But the meme that most of the windiest areas have already been tapped, particularly in No. Germany, is simply false. Public attitudes might need to change some to allow greater density than current, but there remains lots of wind to harvest.

Of course, political problems on land, related to the visual and density issues, are one reason why the EU is pushing so hard for offshore development. But offshore still has some technical hurdles to overcome. I expect within four or five years, offshore will take off explosively.

Take the two together, invest in a European Supergrid which includes linking the entire North Sea, as well as Norway's hydro, and bam, problem solved.
